Features and exemplary embodiments of various aspects of the present application will be described in detail below, and in order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings and the detailed embodiments. It should be understood that the particular embodiments described herein are meant to be illustrative of the application only and not limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the application by showing examples of the application.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

In controlling the operation of a window based on an electronic controller, a stall threshold is often set. In the process of controlling the operation of the window, the operation current for controlling the operation of the window is collected, and the window is controlled to stop moving based on the relation between the operation current and the locked-rotor threshold value. For example, when the collected actual running current in the door and window movement process is larger than the set locked-rotor threshold, the window is controlled to stop moving, and when the collected running current in the door and window movement process is smaller than the set locked-rotor threshold, the window continues to run.

When the locked rotor threshold value is inaccurate, the window cannot be accurately opened or closed to a target state easily, the use experience of a user is affected, and the conditions that the service life of the electronic controller is affected due to heating and the like of the controller of the window are easily caused.

In order to solve the problems in the prior art, the embodiment of the application provides a method and a device for determining the locked-rotor current of an electric window, which can efficiently and accurately set a locked-rotor threshold. The method for determining the locked-rotor current of the power window provided by the embodiment of the application is first described below.

Fig. 1 is a flow chart of a method for determining a locked-rotor current of an electric window according to an embodiment of the present application. As shown in fig. 1, the method may include the following steps 110 to 140.

Step 110, under the condition of controlling the movement of the electric window based on the preset operation voltage, acquiring a data set corresponding to the operation process of the electric window.

The method comprises the steps that a preset operation voltage is associated with an application scene of a preset electric window, the operation process comprises a first operation process from a starting point position to an end point position of the electric window and/or a second operation process from the end point position to the starting point position of the electric window, and a data set comprises a plurality of operation currents of the electric window, which are corresponding to each operation process and are acquired based on a preset acquisition frequency;

Step 120, performing characteristic change analysis on a plurality of operation currents corresponding to each operation process according to a preset calibration rule, and respectively determining the operation current corresponding to a motion stage and the operation current corresponding to a stop stage in each operation process;

Step 130, determining the effective working current of the electric window based on the preset operation voltage according to the operation current corresponding to the motion stage in each operation process, and determining the initial locked-rotor current of the electric window based on the preset operation voltage according to the operation current corresponding to the stop stage in each operation process;

And 140, generating a first target locked-rotor current corresponding to the preset operating voltage according to the average value information of the effective working current and the initial locked-rotor current.

Specifically, the preset operating voltage is associated with an application scenario of the preset power window. Taking a power window disposed in a vehicle as an example, a locked-up voltage required for the power window in a non-started state of the vehicle is different from a locked-up voltage required for the power window in a started state of the vehicle. Therefore, through correlating the preset operation voltage with the application scene of the preset electric window, the finally obtained locked-rotor current is high in accuracy, and the method is more suitable for the application scene of the electric window.

For example, the operation of the power window may include a first operation of the power window from a start position to an end position and/or a second operation of the power window from the end position to the start position. Taking an application scenario in which the vehicle is in an inactive state as an example, the first operation process may be a complete ascending process of the electric window from the bottom to the top, and the second operation process may be a complete descending process of the electric window from the top to the bottom.

In the operation process of the electric window, the operation current of the electric window can be acquired based on the preset acquisition frequency, so that a data set corresponding to the operation process can be obtained. It will be appreciated that when the running process comprises the first running process and the second running process, the data set may comprise in particular a data set corresponding to the first running process and a data set corresponding to the second running process.

After the data set corresponding to the operation process is obtained, characteristic change analysis can be performed on the operation current in each data set according to a preset calibration rule, so that the operation current respectively corresponding to the movement stage and the stop stage of the electric window is determined from the data set.

After the running currents corresponding to the movement stage and the stop stage are determined, the effective working current of the electric window based on the preset running voltage can be determined according to the running current corresponding to the movement stage in each running process;

and finally, generating a first target locked-rotor current corresponding to the preset operating voltage according to the average value information of the effective working current and the initial locked-rotor current.

According to the embodiment of the application, through the preset calibration rule, the operation current corresponding to the motion stage and the operation current corresponding to the stop stage in each operation process can be analyzed and calibrated, and a plurality of different stages in the operation process can be rapidly and accurately calibrated. The method comprises the steps of determining an effective working current of an electric window based on a preset operating voltage according to an operating current corresponding to a motion stage in each operating process, determining an initial locked-rotor current of the electric window based on the preset operating voltage according to an operating current corresponding to a stop stage in each operating process, and finally generating a first target locked-rotor current corresponding to the preset operating voltage according to average value information of the effective working current and the initial locked-rotor current.

In some embodiments, after generating the first target locked-rotor current corresponding to the preset operating voltage according to the average value information of the effective operating current and the initial locked-rotor current, the method further includes:

The predetermined update period may be set to be a period in units of weeks, months, years, and the like, for example, and is not particularly limited herein.

After the first target locked-rotor current is obtained, when the predetermined updating period is set, the method for determining the locked-rotor current provided by the embodiment of the application is combined, and the target locked-rotor current corresponding to the preset operating voltage, namely the second target locked-rotor current, is obtained again.

By calculating the difference value between the first target locked-rotor current and the second target locked-rotor current and determining the preset threshold value, whether the first target locked-rotor current can still meet the current application scene can be known. And particularly, under the condition that the difference value is larger than a preset threshold value, updating the first target locked-rotor current to the second target locked-rotor current. And taking the second target locked-rotor current as the locked-rotor current required by the electric window.

According to the embodiment of the application, whether the locked-rotor current needs to be updated or not is detected regularly, and especially under the condition that the locked-rotor current needs to be updated, so that the rationality of the locked-rotor current setting in an application scene can be ensured, and the problem that the initial locked-rotor current threshold value is unreasonable due to the abrasion of a mechanical structure and the ageing of a friction strip in the use process of the electric window can be effectively avoided.

The step 120 is related to performing feature change analysis on a plurality of operation currents corresponding to each operation process according to a preset calibration rule, and determining the operation current corresponding to the motion stage and the operation current corresponding to the stop stage in each operation process respectively.

Step 1201, sequentially acquiring an operation current set to be analyzed according to a preset sliding window and an acquisition sequence of operation currents corresponding to each operation process.

The length of the preset sliding window is a first preset number, the step length of the preset sliding window is a second preset number, and the running current set comprises running currents of the first preset number;

Step 1202, sequentially analyzing current change characteristics of an operation current set according to a preset calibration rule, and determining a sequential calibration stationary phase, a starting phase, a motion phase and a stopping phase;

Step 1203, extracting an operation current corresponding to a motion stage and an operation current corresponding to a stop stage in each operation process.

By way of example, the operation of the motorized window may be divided into a stationary phase, a start phase, a movement phase and a stop phase. By way of example, fig. 2 is a schematic diagram illustrating a variation of an operating current provided by an embodiment of the present application, taking the above-described movement process of a power window in a vehicle as an example. The current corresponding to fig. 2 is not calibrated yet. FIG. 3 is a schematic diagram of calibration of an operating current according to an embodiment of the present application. As shown in connection with fig. 3, the operating current is at rest 301, at start 302, at motion 303, and at stop 304, respectively.

In some embodiments, the preset sliding window may be understood as a buffer (buffer) queue, where the length of the preset sliding window is the buffering amount of the buffer queue, the buffering amount of the buffer queue is a first preset amount, and the length of the preset sliding window is the first preset amount. For example, the set of operating currents to be analyzed may be obtained using a Buffer, i.e. the first preset number of operating currents may be obtained each time based on a preset sliding window. The step length of the preset sliding window is the number of the pop-up running currents of the cache queue each time, and if the step length of the preset sliding window is 1, the number of the pop-up running currents of the cache queue each time is 1.

Taking a buffer queue with a buffer size of 10 as an example, the first preset number of 10 is that the running current set to be analyzed includes 10 running currents. As shown in the cache line 401 shown in fig. 4, the direction 402 is a moving direction of the cache line, that is, a sliding direction of the sliding window. The running currents are sequentially ordered from first to second according to the sequence of the acquisition time. Continuing to combine with FIG. 4, the Buffer queue is used to obtain the running current set to be analyzed, specifically, the original queue head (i.e. Buffer [0 ]) is popped up in each process of updating the Buffer queue, the data from the original Buffer [1] to Buffer [9] are moved forward by one position to be used as the data from the new buffers [0] to Buffer [8], and then the new data is inserted into the queue tail (Buffer [9 ]).

According to the embodiment of the application, after the running current to be analyzed is extracted each time, the running currents of the electric window can be calibrated into a static stage, a starting stage, a moving stage and a stopping stage in sequence according to the preset calibration rule.

As a specific example, the preset calibration rules involved in the step 1202 may include:

Under the condition that the starting point of the starting stage in the running process is determined, sequentially acquiring a first current change rate of each running current set from the starting point of the starting stage, and determining a first target running current set according to the first current change rate of each running current set. The current change rate of the first target operating current set is smaller than a first threshold value, the first operating current in the first target operating current set is used as an end point of a starting stage, and the second operating current in the first target operating current set is used as a starting point of a movement stage;

Specifically, since the operation currents are analyzed sequentially according to the collection sequence, when the collected operation currents are greater than 0, the electric window is stated to start to move, and the operation process enters the starting stage.

And according to the acquisition sequence, continuously analyzing the running current, wherein the current change rate corresponding to the motion stage is smaller due to the current change rate corresponding to the running current in the starting stage. Thus, the end of the start phase and the start of the motion phase can be determined by analyzing the current rate of change.

Alternatively, the maximum slope of the current value in the running current set corresponding to the fitting function may be used as the first current change rate of the running current set, or the difference between the maximum current value and the minimum current value in the running current set may be used as the first current change rate of the running current set, which is not particularly limited herein.

Under the condition that the starting point of a starting stage in the running process is determined, sequentially acquiring a first current change rate of each running current set from the starting point of the starting stage, and taking the first running current in the running current set as the end point of the starting stage and the second running current in the first target running current set as the starting point of the moving stage when the current change rate of the running current set is detected to be smaller than a first threshold value. Therefore, the operation current corresponding to the starting stage in the whole operation process can be accurately found.

Alternatively, the effective starting current value of the power window may be determined according to the corresponding operating current of the starting phase. For example, a peak value of the operating current may be found from the operating current corresponding to the start-up phase, and the peak value may be used as an effective start-up current value of the power window.

In some embodiments, the analysis of the operating current continues with the determination of the start of the motion phase during operation. Since the rate of change of the corresponding operating current in the stop phase is relatively large with respect to the rate of change of the corresponding operating current in the motion phase, the end point of the motion phase and the start point of the stop phase can be determined by analyzing the change of the current rate.

Alternatively, the maximum slope of the current value in the running current set corresponding to the fitting function may be used as the second current change rate of the running current set, or the difference between the maximum current value and the minimum current value in the running current set may be used as the second current change rate of the running current set, which is not particularly limited herein.

According to the embodiment of the application, the operation process of automatically calibrating the electric window can be realized, the accuracy is high, and the calibration efficiency can be effectively improved.

In order to further improve the accuracy of the calibration result, the integrity check can be performed on a plurality of currents corresponding to the operation process. The method comprises the steps of extracting running current corresponding to a motion stage and running current corresponding to a stop stage in each running process, and determining a first duration corresponding to the stationary stage, a second duration corresponding to the start stage, a third duration corresponding to the motion stage and a fourth duration corresponding to the stop stage according to the quantity of the running currents corresponding to the stationary stage, the start stage, the motion stage and the stop stage respectively.

In some embodiments, when the first time length is not less than the first preset time length or the second time length associated with the stationary phase is not less than the second preset time length or the third time length associated with the starting phase is not less than the third preset time length or the fourth time length associated with the moving phase is not less than the fourth preset time length associated with the stopping phase, controlling the movement of the electric window again based on the preset operation voltage, and acquiring a data set corresponding to the operation process of the electric window.

In other words, when the running process is in a stage for more than a certain time, the movement of the electric window is judged to be incomplete in the running process of the electric window, so that large errors are easily caused in the locked-rotor current, and the locked-rotor current is determined after the running current is acquired again.

In some embodiments, the effective operating current of the preset operating voltage includes an effective operating current corresponding to a first operating process in a case where the operating process includes a first operating process from a start position to an end position of the power window, and includes an effective operating current corresponding to a second operating process in a case where the operating process includes a second operating process from the end position to the start position of the power window. Referring to the above step 130, the following steps may be specifically referred to.

In step 1301, the number M of the first target sliding windows and the number N of the second target sliding windows are acquired.

The first target sliding window is a preset sliding window corresponding to a movement stage in a first operation process, and the second target sliding window is a preset sliding window corresponding to a movement stage in a second operation process.

And 132, calculating the average value of the running current in each first target sliding window to obtain M first average values under the condition that the number M and the number N are larger than or equal to a first number threshold value, and calculating the average value of the running current in each second target sliding window to obtain N second average values.

In step 1303, the average value of the M first average values that are the smallest in the M first average values is calculated to obtain an effective working current corresponding to the first operation process, and the average value of the M second average values that are the smallest in the N second average values is calculated to obtain an effective working current corresponding to the second operation process.

Specifically, taking a first operation process from a starting point position to an end point position as an example, when calculating the effective working current, by calculating the number M of the first target sliding windows, judging the relationship between the number M of the first target sliding windows and the first number threshold value, whether the operation process is abnormal or not can be judged, when the number M of the first target sliding windows is smaller than the first number threshold value, the operation process is described as abnormal, and if the effective working current is continuously calculated, the reliability of the calculated effective working current is low. Under the condition that the number M and the number N are larger than or equal to a first number threshold value, calculating the average value of running currents in each first target sliding window to obtain M first average values; and calculating the average value of the running current in each second target sliding window to obtain N second average values.

As a specific example, taking a first operation process from a start position to an end position of the electric window as an example, the number of first target sliding windows acquired in the first operation process is denoted as M.

The first number threshold may determine whether an operation process is abnormal, for example, the first number threshold=40, when the number M of the first target sliding windows is less than 40, which indicates that the operation process is abnormal, if the effective working current continues to be calculated, the reliability of the calculated effective working current is low, and the data set corresponding to the operation process of the electric window may be selected to be re-acquired, so as to obtain the reliability and obtain the first target blocking current.

In some embodiments, a temporary array for storing the first means may be preset, after the M first means are calculated, the M first means are stored in a preset temporary array (sz_buffer), and the M first means are sorted in a monotonically decreasing manner, so that the minimum M first means may be extracted therefrom, so as to calculate the average of the minimum M first means, and obtain an effective working current corresponding to the first operation process. For example, it may be taken that m=10, and a minimum average value of 10 first average values is calculated, so as to obtain an effective working current corresponding to the first operation procedure. Optionally, a temporary array for storing the second mean value may be preset, after the N second mean values are obtained by calculation, the N second mean values may be stored in the temporary array, and the N second mean values may be sorted in a monotonically decreasing manner, from which the smallest N second mean values may be extracted, so as to calculate the average value of the smallest N second mean values, and the effective working current corresponding to the second running process may be obtained. It is understood that M is greater than M and N is greater than N.

The electric window is in a second operation process from the end position to the start position, and the number of second target sliding windows acquired in the second operation process is recorded as N. The first number threshold may also determine whether the second operation process is abnormal, for example, the first number threshold=40, when the number N of the second target sliding windows is less than 40, which indicates that the operation process is abnormal, if the effective working current continues to be calculated, the reliability of the calculated effective working current is low, and the data set corresponding to the operation process of the electric window may be selected to be re-acquired, so as to obtain the reliability and obtain the first target locked-rotor current.

In some embodiments, a temporary array for storing the second mean values may be preset, after N second mean values are obtained by calculation, the N second mean values are stored in a preset temporary array (sz_buffer), and the N second mean values are subjected to monotonically decreasing sorting, from which the smallest N second mean values may be extracted, so as to calculate the average value of the smallest N second mean values, and obtain the effective working current corresponding to the second operation process. For example, it may be taken that n=10, and a minimum average value of 10 second average values is calculated, so as to obtain an effective working current corresponding to the second operation procedure.

In some embodiments, in the case that the operation process includes a first operation process from a start position to an end position of the electric window, the initial locked-rotor current of the preset operation voltage includes an initial locked-rotor current corresponding to the first operation process;

The step 130 may include determining an initial locked-rotor current of the electric window based on a preset operation voltage according to an operation current corresponding to a stop stage in each operation process, and specifically may include obtaining a peak value in the operation current corresponding to a motion stage in a first operation process to obtain the initial locked-rotor current corresponding to the first operation process, and obtaining a peak value in the operation current corresponding to the motion stage in a second operation process to obtain the initial locked-rotor current corresponding to the second operation process.

According to the embodiment of the application, the initial locked-rotor current corresponding to the first operation process can be rapidly determined by acquiring the peak value in the operation current corresponding to the motion stage in the first operation process. And obtaining a peak value in the running current corresponding to the movement stage in the second running process, so that the initial locked-rotor current corresponding to the second running process can be rapidly determined.

In some embodiments, referring to step 140, generating, according to average information of the effective working current and the initial locked-rotor current, a first target locked-rotor current corresponding to a preset operating voltage may specifically include:

Step 1401, under the condition that the operation process comprises a first operation process from a starting point position to an end point position of the electric window and a second operation process from the end point position to the starting point position of the electric window, calculating the average value of effective working current corresponding to the first operation process and initial locked-rotor current corresponding to the first operation process to obtain a first average value;

step 1402, calculating the average value of the first average value and the second average value, to obtain a first target locked-rotor current corresponding to the preset operating voltage.

The effective stall current is typically greater than the operating current of the power window during normal operation, greater than the starting current of the power window, but less than the actual stall current by one current value. In order to improve the reliability of the target locked-rotor current, after obtaining a first average value of the effective working current of the first operation process and the initial locked-rotor current corresponding to the first operation process and a second average value of the effective working current corresponding to the second operation process and the initial locked-rotor current corresponding to the second operation process, continuously calculating the average value of the first average value and the second average value, and taking the average value of the first average value and the second average value as the first target locked-rotor current, thereby effectively improving the reliability of the locked-rotor current provided by the embodiment of the application, avoiding the situation that an electric window cannot completely return to a starting point and cannot reach an end point, and also avoiding the electric window entering a thermal protection state in the middle to stop operation.
